Abstract
Straie distensae lesions may be prevented and/or reduced in size by topically applying to the skin affected with the lesions an effective amount of retinoic acid, preferably by daily application in a dermatologically acceptable vehicle, such as a cream base, at a concentration of about 0.025 to 0.1 weight percent. When applied during the straie rubrae stage, the retinoic acid may be effective to prevent the formation of straie albae lesions, and when applied in either stage, the retinoic acid may be effective to reduce the width and depth of the lesions, with improved texture and softness.
